I have scoured the internet trying to find an installation guide to this mod chip, but to no avail. The site that it was purchased at, apple-chip.com is no longer active. The chip is apple-x, not applex V or any other variant of, just simply says apple-x.
Here's a picture of it, I'm currently trying to use the diagram from a similar (looking) modchip to install it, we shall see how it goes.
(sorry for the blurry pic, it was taken with my phone.)
I guess the reason for my post is to see if anybody has every seen this thing before or if anybody has a clue as to how to solder this bad boy.
